Conditionally execute a statement.
IF binary_result then statement
IF binary_result else statement
The binary_result is something that can be set to true or false, i.e. 1 or 0. The operators AND , OR , EQ , NE , LT , LE , GT , GE and = are all supported as in jBC code. The IF statement does not supported nested statements. The THEN or ELSE clause must be followed by the statements to execute. If no statements follow, then this is the equivalent of a "No Operation".
IF result THEN PRINT "result was non-zero, exiting" ; exit
if elapsed GT 10 AND warning_flag THEN goto errorlabel
if (var EQ A:B OR var EQ C:D) AND msgflag THEN PRINT "hello"
